The "What if Marvel Bought DC" thread got me thinking ... if they merged 616 and the DC universe, what would be your ultimate Avengers lineup?
Limit to 12 roster slots or less.
For me, I think I'd take:
Green Lantern (Jordan)
Flash (Barry Allen)
No Batman. Batman always bugged me on JLA ... it's not because he "doesn't have powers" as his detractors always lament ... it's because his gimmick is the whole secrecy thing. It never made sense for him to be under-the-radar in his own title, and then parading around with Superman on a satellite in JLA.
I could easily go with others instead of Pym/Van Dyne in terms of their power set, but to me, Giant-Man and the Wasp are in for nostalgia sake, and to keep things with that Avengers-feel.
Man, DC has a lot of heavy-hitters. The classic JLA lineup (Supes, Bats, GL, WW, MM, Aquaman, Flash) is pretty top-heavy, when you've got regular guys like Batman or Green Arrow, and then the next step up in power is the Flash, who can literally run back in time. Over 70% of the core JLA lineup is in the benchpressing-a-tank class. One of the reasons I always liked the Avengers - a balanced squad. But I'm probably Marvel-biased
So anyway, with my team, I'd split them into two squads. B-Team would be my stealth squad, good for infiltration and such, but more than able to handle all but the top-level threats:
Cap, Pym, Barton, Van Dyne, and Flash
The rest are A-Team, any of them able to individually respond to crises across the globe, or come together to defeat Galactus, Darkseid, or whoever else gets in their way.
